Question
Answer the following question.
Distinguish between real and pseudo force.
Solution
| Real force | Pseudo Force | |
| 1. | A force which is produced due to interaction between the objects is called real force. | A pseudo force is one which arises due to the acceleration of the observer’s frame of reference. |
| 2. | Real forces obey Newton’s laws of motion. | Pseudo forces do not obey Newton’s laws of motion. |
| 3. | Real forces are one of the four fundamental forces. | Pseudo forces are not among any of the four fundamental forces. |
| 4. | Example: The earth revolves around the sun in a circular path due to the gravitational force of attraction between the sun and the earth. | Example: Bus is moving with an acceleration (a) on a straight road in forward direction, a person of mass ‘m’ experiences a backward pseudo force of magnitude ‘ma’. |
